Abstract

To provide a liquid crystal display device capable of outputting a sound of a sufficiently large volume by use of a liquid crystal cell which displays an image. A liquid crystal display device includes a thin front glass substrate having an outer surface in which a rib is formed on a peripheral portion, a back glass substrate arranged with a predetermined gap from an inner surface of the front glass substrate, in which liquid crystal is sealed in the gap, and a sound source element provided in contact with the front glass substrate.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a liquid crystal display device of a liquid crystal television set, a liquid crystal display for a cellular phone, and the like, which performs a display by modulating a linear polarization state, and more specifically, to a liquid crystal display device capable of outputting an audio from a screen itself.

[0002] In recent years, liquid crystal display device technology, and particularly, liquid crystal display device technology using color display elements has significantly progressed. In the liquid crystal display device, downsizing / thinning, weight reduction, and further, lower power consumption, can be achieved. Accordingly, demand for liquid crystal display devices has rapidly expanded. Such a liquid crystal display device has a configuration in which an element (liquid crystal cell) formed by sandwiching a liquid crystal layer between a pair of glass substrates is provided, and polarizing plates are attached o...
